Hi,
I have a distributed volume with 6 bricks, each have 5TB and it's hosting large qcow2 VM disks (I know it's reliable but it's not important data) I started with 5 bricks and then added another one, started the re balance process, everything went well, but now im looking at the bricks free space and i found one brick is around 82% while others ranging from 20% to 60%. The brick with highest utilization is hosting more qcow2 disk than other bricks, and whenever i start re balance it just complete in 0 seconds and without moving any data. What will happen with the brick became full ? Can i move data manually from one brick to the other ? Why re balance not distributing data evenly on all bricks ?
